No, OLD was ANSI standard, following Dartmouth BASIC, the original BASIC.

This is what your computer is trying to tell you: Seriously, have a look here: http://atariage.com/forums/topic/254749-greasy-cartridge-port/?do=findComment&comment=3553078 One of the 4116 [email protected] has failed. [email protected], U102 which is @ll the way over to the left by the joystick pnrt. Replacing it will take some desoldering skills (this is a great way to start with electronics.)

Well, I got the $11 crimping tool (for open barrel contacts) at Altex. No ratchet. It did the job, with extra hands. Amanda now has the amended title "Chief Sloth of Communications and Crimping." Unfortunately, Altex is like an electronics candy store, and I spent $40 on stuff I didn't necessarily need right away. So the cheap crimping tool sort of cost $50 anyway.

My FORTH story: the TI FORTH package , disks and manual, was dropped off by a TI employee who said "you have to see this demo". What is this!??! How does it work? My older brother and I followed the getting started instructions in the manual. It became clear that we needed a user floppy disk. We had only one disk candidate: my new program save disk, purchased for the enormous sum of $1.99 at JC Penney, on which I had saved working copies of an all new, large sprites version of TI-TREK. I think we owned like 8 floppy disks in total. Even the disk drive was on loan from TI to our boy scout troop (TI made it a gift eventually.) My brother insisted it would be fine if we used my disk. I was not so sure. In the end, I gave him the disk. TI FORTH ate it. The files were gone and there were Klingon CALL CHARs on the user screens. I was sad. I never worked on another TREK game. But we moved on to programming bitmap mode in FORTH. Yay.

Oh heavens, I never knew this existed, despite browsing the DataMath site a lot for reference: Texas Instruments Stack Around Clown, Le Clown Magique, Magic Clown, Chatter-Ring Clown http://www.datamath.org/Speech/StackARoundClown.htm

I am just old enough to remember when TI watches were cool.. never mind that typewriter looking thing around the corner.

It's a sidecar 32k OR paraPrint18 from Doryt. Goodwill didn't take a whole photo. The funny thing is the assymetrical ON-OFF instructions on the sticky note. See here: https://www.atarimagazines.com/compute/issue39/259_3_NEW_PRODUCTS_MEMORY_EXPANSION_AND_PRINTER_INTERFACE_FOR_TI-99_4A.php

Hey all, Every time you mention a game in this thread, a bell rings, and the game gets a ticket into a very special game heaven ruled by King Knut Polyoptics. (The first game to get in was Cars & Carcasses II, Knut's favorite.) But the door is only 8x8 pixels wide so only some of the sprites get into heaven. Unfortunately, Zero Zap de-rezzed because it did not fit. Oh no. Also the red monster from The Attack failed, though the spores got in and are giving MunchMan the hay fever. King Knut is angry about this loss of pixels, but so far none of his angels or valkyries or dwarves (or all the King's horses) have fixed it. For now it's strictly 8-bit heaven. Keep it coming.

Hi all, We're planning another trip to Portland soon, like in May. If y'all pick a date for FestWest there's a chance I can attend! I would bring the work in progress of FORTI-2 hardware (it runs! sort of), and a fun bitmap scroller game that I just had to write (thanks, RetroChallenge 2019.)

Are you saying you want a ZeroZap 2?

I'm still using FlashROM and it's good enough for me. I use actual cartridges with GROMs like E/A, XB, MiniMemory, games. Sure I'd like to get a FinalGROM, but there were so many upgrade priorities (hmm WICO joysticks)

I've been playing Zero Zap. It's growing on me. My high score is 541 so far.

It just occurred to me that I can just plug in Tunnels of Doom, load a game from DSK1, then save to CS1. Duh. I am all set up with cassette recorder on my desk these days (cassettes are cool again?)

(Posting in TI-99/4A because it's my home page) I had never used a crimping tool until now, only solder. But I'm making an arcade joystick console, and the buttons and stick (links to Ultimarc) have quick disconnect terminals. So I got a $10 crimping tool at Lowe's and made a wiring harness. (The buttons use 2.8mm quick disconnect terminals, which are not common. Don't forget to buy these when buying buttons! Fortunately I had a box from an estate sale.) So now for the 9-pin D-sub connector that plugs into the joystick port! I have only used solder-cup 9-pin connectors, but I picked up these at Fry's. (Fry's is a giant electronics store that is both a train wreck and a lifesaver at the same time.) 9 Pin Female Crimp Style D-Sub RS232 Female Contact Pins So how the heck do I crimp those contacts onto wire ends? My trial efforts are miserable. I need another tool. I found this video showing closed-barrel D-sub contacts. I'm not sure if the tool works for these Fry's open-barrel or Dupont contacts. This 4-indent, closed barrel pin crimping tool costs $50. (I saw the tool chained down in one video.) https://www.grainger.com/product/GREENLEE-COMMUNICATIONS-6-1-2-L-Crimper-4NHR5 I think I need the SN-28B ratchet tool used here. It's more reasonable for $22 I'm about to give up and just go buy solder-cup 9-pin D-sub. Advice? Before I throw any more money into a crimping tool? Will it just give me more grief?

I sunk many hours into beating this game as a kid. The worst thing about it was the requirement to jump from exactly the right pixel.

That will connect perfectly.

The picture you show, that's what you refer to as a pigtail? The 4 pin Molex cable? The replacement power supply xabin refers to is the Radio Shack/Archer-branded QI supply (new-in-bag) and has the 4 pin header on the board. The alternative was a non-QI supply board (taken out of a working beige console that was sacrificed for parts) also with the same 4 pin header.

Received this today: https://www.halted.com/commerce/index.jsp Surplus store HSC has sold to Excess Solutions. I noticed they sell the AMI S9900 for $15.50. http://www.excesssolutions.com/cgi-bin/item/ES2878

Enjoying the scrolling! Practical question: how are you capturing the video to upload?

I'm a laser guy.. not a 3D printing guy.. it seems a lot easier to me to laser a rectangular panel out of sheet acrylic, with a second layer jig that also fits snugly around whatever jack is present. Cost of material: 25 cents. Time to produce: cut dozens of them in a few minutes batch job. My beige is not an exact match for TI beige. Black acrylic is cheap. This would work for new mods (or covering up unsightly holes) I'm not going to be removing my F18A either (its super valuable and useful! never obsolete!). I will just mod another console for an F18A mk2.
